Fix

Add forward-declaration of the function:

... Header and Comments

#include "raylib.h"
#include <stdlib.h>         // Required for: rand()
#include <math.h>           // Required for: cos(), sin()

#define MAX_POINTS 10000000 // 10 million
#define MIN_POINTS 1000     // 1 thousand

static float RandFloat();

// Forward-declare function
Mesh GenPoints(int numPoints);

... Rest of example

@zmertens this issue should be already fixed.
